Super-Scaling Network File Systems with SAN-Based Distributed File Systems

The concepts used in cluster file systems and NAS clusters can be extended to larger network file system implementations. A distributed file system (DFS) is another variation on the traditional file system design. A DFS runs the various functions of a file system on multiple systems that communicate over one or more networks.

Distributed file systems address several fundamental storage requirements and storage management needs. First and foremost, they provide excellent file system scalability without risking data loss due to system failures. Second, they provide excellent throughput for distributed applications such as cluster or grid-based databases. More importantly, ...
